Hello.
We are using Azure Remote Rendering in our Unity application for HoloLens2 and facing the following error.
As the error message indicates, the error occurred when we tried to connect more than 8 HoloLenses to the same ARR account at the same time.
[Error]
Azure.RequestFailedException: Could not create session - Exceeding the maximum active session limit of 8. Please refer to the Azure Remote Rendering documentation for more infomation.
Status: 400 (Bad Request)
at Azure.MixedReality.RemoteRendering.RemoteRenderingRestClient.CreateSessionAsync(Guid accountId, String sessionId, RenderingSessionOptions body, CancellationToken cancellationToken) at Azure.MixedReality.RemoteRendering.RemoteRenderingClient.StartSessionAsync(String sessionId, RenderingSessionOptions options, CancellationToken cancellationToken)
[Environment]
Unity: 2021.3.5f1
Azure Remote Rendering SDK: Ver 1.1.0
Azure Remote Rendering Region: Japan East
Azure Remote Rendering Server size: Premium
Model to be rendered: Point cloud
And, we would like to know the followings:
- Where can we find the maximum active session limit information on the ARR official document?
(I could not find the information about the maximum active session on the document.) - Is it possible to allow more active sessions to connect if we request an ARR's quota increase?
It would be appreciated if we could get some answers to the above questions.

Thanks for bringing this to our attention. We'll do some further investigations on what's the fastest way to increase the limit. May I ask what's the order of magnitude of number of sessions you'd like to run simultaneously?
Unfortunately the limit is not documented in the REST SDK / public documentation yet, we'll improve this.As a very short term workaround until we have raised the limit, you could create more ARR accounts on your subscription, since the limit is based on account ID.

2023-11-09T03:20:51.19+00:00 Hello Florian,
Thank you for answering my question.May I ask what's the order of magnitude of number of sessions you'd like to run simultaneously?
With regards to your question, we would like to run 20 sessions simultaneously.
From your answer, we now understand that we can allow to connect more sessions at the same time if we create more ARR accounts.
However, we think it would be better if we could allow to connect more sessions in a single ARR account because it reduces the cost of managing the number of sessions in multiple ARR accounts.And, I would like to clarify the situation when the active session limit error occurs.
- Is the limit based only on the ARR account ID and not on the session type (Standard or Premium)?
[e.g] In any of these cases, it is not possible to create the 9th session and the active session limit error occurs.- An ARR account has already 8 Standard ARR sessions
- An ARR account has already 4 Standard ARR sessions and 4 Premium ARR sessions
Thank you for helping us learn more about ARR. We look forward to seeing the results of the investigation.

fully agree we should do something about the limit in the first place.
The limit is...
- ...per account Id,
- ...independent for session size and usually larger for 'standard'. So you can have 8 premium + x standard sessions simultaneously. In your region the limit for 'standard' is 32.
- ....per region. So you could allocate the first 8 premium sessions in your region and if it starts failing use the next closest region. Not sure if using a fallback region is an option for you?
Best Regards!

Thank you very much for sharing the infomation on the limit.
We understand the details of the limit and how to increase the limit by creating multiple ARR accounts.We would appreciate any information on the fastest way to increase the limit once the investigation is complete.

yes, we are still investigating what is the best solution here. It takes a bit more time because it's a common effort in Azure, not just the ARR team.
In the meanwhile as a workaround, I'd recommend the multiple account approach plus fallback into a different region in case you reach capacity limits.
I'll keep you updated!

I'm the product manager for Azure Remote Rendering, I'd love to make sure you have what you need to be successful here. Can you please open a support ticket through the portal for Azure Remote Rendering? I'll make sure to get it routed my way so we can connect directly. Thank you, -Andrew

Sorry for the delayed response! We were able to increase the per-account limit of Premium sessions from 8 to 16 in your region. I know this is not where you need to be, but I hope it's a good start ;-)
We will keep in touch regarding further improvements!
Cheers!
Florian

Hi Andrew, I'm sorry for the delayed response.
We couldn't create a support ticket through the Azure portal and our cloud service provider told us that we can still contact you via email.
We will contact you via email instead of a support ticket.
